Switchable and tunable chiral metamaterial response is numerically demonstrated here in different uniaxial chiral metamaterial structures operating in the THz regime. The structures are based on the bi-layer conductor design and the tunable/switchable response is achieved by replacing parts of the metallic components of the structures by photoconducting Si, which can be transformed from an insu...

In this paper, we represent numerical results which, validate our former work on the hydrodynamic effect (nonlinear) produced by breaking waves [1] in EM bistatic scattering coefficients. We calculated the scattering coefficient σ HH of breaking waves in bi-static configurations as a function of time. Then, in this paper we represent the first experimental measurements, which have been carried ...

Non-supersymmetric orbifolds of N = 1 super Yang-Mills theories are conjectured to inherit properties from their supersymmetric parent. We examine this conjecture by compactifying the Z2 orbifold theories on a spatial circle of radius R. We point out that when the orbifold theory lies in a specific weakly coupled vacuum, fractional instantons do give rise to the conjectured condensate of bi-fun...

We study the computational capabilities of a biologically inspired neural model where the synaptic weights, the connectivity pattern, and the number of neurons can evolve over time rather than stay static. Our study focuses on the mere concept of plasticity of the model so that the nature of the updates is assumed to be not constrained. In this context, we show that the so-called plastic recurr...

In two-parameter systems two symmetry breaking bi-furcation points of diierent types coalesce generically within one point. This causes secondary bifurcation points to exist. The aim of this paper is to understand this phenomenon with group theory and the innerconnectivity of irreducible representations of super-group and subgroups. Colored pictures of examples are included.

We here explicitly write down the Feynman rules following the work of Dijkgraaf, Vafa and collaborators for N = 1 super Yang-Mills having products of SU groups as the gauge group and matter chiral superfields in adjoint, fundamental, and bi-fundamental representations without baryonic perturbations. As an application of this, we show expectation values calculated by these methods satisfy the Ko...
